제목 Highly Ordered Mesoporous Niobium Nitride for High-Performance Anode Material in Potassium-Ion Batteries
초록 Although Lithium-ion batteries (LIBs) have been regarded as fascinating energy storage device, the scarcity and high cost of lithium resources intrigue researchers’ interest in the next-generation batteries such as Potassium-ion batteries (KIBs) which have similar electrochemical characteristic of LIBs and use abundant potassium resources. However, to date there are still significant problems about searching suitable anode materials for KIBs because of hazardous of potassium metals and unstable cycle performance of carbonaceous materials due to large ionic size of potassium. Herein, we report ordered mesoporous niobium nitride/N-doped carbon composites hybrids (m-NbN/NC) as anodes for KIBs with superior cyclability and rate capability. This work may suggest feasible new class of anode materials for ultra-stable KIBs.
